[yt-users] Loading RAMSES Data into yt.

[Matthew Turk]

Hi Kearn,

I think Romain's suggestion is likely going to fix the issue, but I
also just pushed a change that will show the error differently and in
a more informative way.  ("hg pull
http://bitbucket.org/yt_analysis/yt-3.0 && hg up" in your yt-hg
directory will fix it.)
